JSON UI
A universal JSON-to-UI rendering engine. One JSON spec renders as a web page, PDF document, or inline AI chat component.
JSON UI defines a component catalog with typed props, maps it to design-system components via registries, and renders specs using the json-render framework. AI models generate specs constrained to the catalog, ensuring native UI output.
Three rendering targets:
- Web — renders specs with design-system components (available now)
- PDF — exports specs as downloadable PDF documents (coming soon)
- AI Chat — streams specs inline within AI conversations (coming soon)
